What is the classification standard of edible fungi.

The fresh mushrooms of edible mushrooms should be harvested by medium well, but they should be determined according to the requirements of specific merchants, and should not be generalized. The overall requirements should be: 1. Strains (varieties) in the right way; 2. The matrix meets the requirements; 3. Within 1000 meters of the cultivated land, there are no chemical industry, hospitals, livestock and poultry farms, garbage disposal stations, waste piles, manure treatment plants, etc. The residue of cultivated API is less than or equal to the relevant standard; 5. No illegal drugs or additives are used in the cultivation process; 6. Equipment, tools, materials, etc., do not contain prohibited ingredients; 7. Fresh mushrooms are not aging, no moth-eaten eggs, no diseases and so on. The following is a brief description of the classification standards of four kinds of edible fungi for readers' reference.
